I don't understand what I would be letting myself in for if I took up knitting or sky diving. But that doesn't make me stupid. I think I know what knitting and sky diving mean but I'm sure once I did them, my understanding and perspective would alter.

Please Mr Hertford, don't purposely confuse perception with understanding or commenting with opinion. It doesn't do you any favours, especially when you are trying to put forward an absurd narrative of history.
